compost is new horizons organic – and has been dutifully firmed into the modules – all other module growth is and has been healthy –
However on the lettuce modules there has been a lot of fungal fruiting (tiny little ‘cups’) on the compost surface –
I think with the wilting yesterday – the modules were too dry , i was concerned about over watering! They hadn’t been watered for a few days, and i only gave them a light watering (not enough to soak) , before the wilting occured. Then a good soak remedied.
Also the wilting usually occurs at the edge of trays, and at worst towards the south side of the tunnel, the shelves and tunnel run east west.
Generally though here in our sheltered steep south facing valley i notice (due to sun trap effect) , when the sun is out it feels much stronger and more intense than elsewhere. Even this morning i am now in a tshirt.
Also our tunnels have anti-fog thermal plastic on them – so perhaps they get hotter than normal plastic?
But these factors combine to make it tricky, as plants need more water to cope with the intense hot periods, and then stay damp when sun goes.
Lettuces are outside now in some glorious autumn sunshine, so i hope over the next few days they recover!
